c# reading xml file

Question

I am trying to pull the <thumbnail_large>http://b.vimeocdn.com/ts/235/662/23566238_640.jpg</thumbnail_large> value from the thumbnail_large element in a created xml file. Is there a way to pull that value without looping through the who xml file? Thanks for any help.

Answer 1

Yes, there is and it is called XPath. Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"/path/to/file");
XmlNode node = doc.SelectSingleNode("/videos/video/thumbnail_large");
string URI = node.InnerText;

At least that is what I can read from this poorly formatted file. If you are using two different alphabets (video details and HTML markup) you should consider using namespaces.
